Hey I’m sorry for what you are going through. My career was destroyed by hyperacusis. The tinnitus in my left ear is like a dentist drill and I’m deaf above 4kHz. My hyperacusis makes it difficult to carry on a conversation indoors. I’m better outside without reflective surfaces. My right ear is still good. I went for corrective surgery at the Silverstein Institute and they said that I have a hyper mobile stapes bone, the result of acoustic shock. In my case it was an explosion on a film set that did the initial damage. Then I shot a deer without hearing protection a few months later. The symptoms started about a day later with sudden onset hearing loss, tinnitus and hyperacusis during a conversation. My surgery was not successful and I’m still suffering hyperacusis which is much worse than the dentist drill in my ear. I cannot go inside a room with people inside without hearing protection. S and t plosives during conversation are like starting at the sun. Just painful. I also am a musician with a recording studio and have a mixing room tuned for my needs so that I can still play amplified music on the other side of the glass.
Good luck, it’s been almost ten years for me and I’m getting better mentally, and noise canceling AirPods with a little white noise or rain sounds help if I have to go inside a room full of people.
